Fuel Efficiency Analysis
The Weichai WD615 engine incorporates high-pressure common rail (HPCR) fuel injection and an optimized combustion chamber design, enabling precise fuel metering and reduced specific fuel consumption (SFC). Under mixed-load operating cycles (digging, swinging, loading), the excavator achieves:
- Average Fuel Consumption: 28–32 L/h
- Fuel Efficiency Gain: ~12% improvement over previous-generation models (WD615.61) due to ECU tuning and load-sensing hydraulic system integration
- Idle Fuel Savings: Auto-idle function reduces consumption by up to 18% during non-productive cycles
This results in approximately 1,800–2,200 L fuel savings per 1,000 operating hours compared to non-optimized platforms, translating to significant cost reduction in large fleet operations.
Load Capacity & Structural Performance
The CAT-class excavator is engineered for high-dynamic-load environments, featuring a reinforced undercarriage and stress-optimized boom/arm assembly. Key load-related performance metrics include:
- Maximum Digging Depth: 7.8 m
- Bucket Capacity (HE): 4.5 m³ (Standard) / 6.2 m³ (Optional Rock Bucket)
- Swing Torque: 85 kN·m (Planetary Gear, Two-Speed)
- Drawbar Pull: 285 kN (1st Gear, Full Traction)
- Gradeability: 30% (Loaded, Hard-Packed Surface)
The HW19710 transmission provides robust torque transfer with minimal slippage, ensuring consistent power delivery under peak load. Axle load distribution is optimized to maintain traction and reduce tire wear, even on uneven terrain.
Conclusion
This CAT-class excavator platform, powered by the Weichai WD615 engine and paired with the HW19710 transmission, delivers industrial-grade reliability, high load capacity, and measurable fuel efficiency. With a gross axle load rating of 25,000 kg and 12.00R20 radial tires supporting heavy payloads, the machine is ideal for quarrying, mass excavation, and infrastructure projects requiring sustained high-output performance. Fleet managers can expect reduced operational costs and extended service intervals, enhancing total cost of ownership (TCO) across deployment cycles.

Note: Flat Rack costs vary significantly based on destination port surcharges and inland transport logistics.
4. Corrosion Protection: Wax Spraying Protocol
Marine environments pose a high risk of saltwater-induced corrosion to excavator undercarriages, hydraulic cylinders, and exposed steel components. SEA LION International recommends the following anti-corrosion wax spraying protocol prior to shipment:
4.1 Wax Application Specifications
| Parameter | Requirement |
|---|---|
| Wax Type | Solvent-based, hydrophobic corrosion inhibitor (e.g., Woolwax™ or Dinitrol AV-17) |
| Coverage Areas | Undercarriage, track links, boom/stick pins, hydraulic rods, cab underside |
| Application Method | High-pressure spray (250–300 psi) |
| Dry Film Thickness | 50–75 µm (microns) |
| Curing Time | 24 hours (ambient 20°C, 50% RH) |
| Salt Spray Test (ASTM B117) | Pass: 500+ hours |
4.2 Post-Treatment Procedures
- Drainage: Ensure all water traps (e.g., track frames, counterweight cavities) are drained.
- Sealing: Protect electrical connectors with dielectric grease and plastic caps.
- Documentation: Include wax treatment certificate in shipping dossier for customs and end-user verification.
Compliance Note: Wax-treated units must be labeled “Corrosion-Protected – Do Not Wash Before Commissioning.”
5. Method Recommendation by Use Case
| Fleet Profile | Recommended Method | Rationale |
|---|---|---|
| Large-volume new equipment | RO-RO | Cost/time efficient; minimal handling; ideal for operable units |
| Single or oversized units (>80t) | Bulk Cargo | No weight restriction; direct deck stowage |
| High-value, precision-used units | Flat Rack + Wax Spray | Full control over securing; optimal for mixed cargo or port-limited zones |
| Projects with tight commissioning | RO-RO + Wax Spray | Fast discharge; reduced reconditioning; operational readiness |
6. Operational Best Practices
- Pre-shipment Inspection (PSI): Conduct ISO 9001-aligned verification for fuel/oil levels, battery isolation, and safety latches.
- Lashing Compliance: For Flat Rack, adhere to CSS Code (IMO) and DNV-ST-E301 for securing forces (minimum 1.2g longitudinal).
- Voyage Monitoring: Utilize IoT-enabled GPS and humidity sensors in containerized shipments.
- Port Coordination: Confirm receiving terminal RO-RO ramp availability or heavy-lift crane capacity (≥100t) in advance.
7. Conclusion
For high-volume export of CAT excavators from China, RO-RO shipping offers the optimal balance of cost, speed, and safety for operable units. Bulk cargo remains viable for oversized or non-functional equipment, while Flat Rack containers provide maximum control for high-value or irregular shipments. In all cases, industrial-grade wax spraying is a non-negotiable step to ensure equipment integrity across saline maritime routes.
Fleet managers and construction logistics teams are advised to integrate corrosion protection into procurement-to-delivery workflows to minimize reconditioning costs and downtime.
